Rice Mapping using Sentinel 1, 2 in Earth Engine [GEE]

In this video we follow the codes from the paper for rice mapping process.

The basic idea is to include the monthly images from Sentinel 1 and 2 in rice growing period. The monthly images from both the Sentinel 1 and 2 are stacked as the image. The stacked image is clustered from the unsupervised method. The spectra of the clusters are observed, and the rice pixels are identified.

Challenges during this method might be the presence of the clouds during the rice growing period. Also the method is not suitable for larger area, by larger area meaning the whole country, or even a district of any country.

This video is likely to be helpful for anyone wishing to build concepts of rice mapping process using Sentinel 1 and 2. You can follow the methods and shared codes from the paper for the study of the methods.
